I spent an hour or so looking at images for BP...I saw a few pics, back views or ones with something obscuring a face, that resemble Alexis's appearance, size shape, and coloring.
I was intrigued by one site, linked to my search (B@ckpage 5'7" cocoa.) There were quite a few pictures that resembled Alexis. The site was lukeslist, Atlanta, GA.
I also saw a few attached to BP Central NJ, New Jersey, Ohio, Indianapolis and New York. But, like I said, the pics were either taken from the back or had obscured the faces.
Sadly, if they took Alexis, for the purpose of the sex trade, she could be in any major city or being moved from one city to the next. I doubt she is being used in a club or for parties.
Note: Even with "safe search" on, very graphic photos case up in the image search..
